Find an equation of the line with the slope m= - 8 that passes through the point (-3,-6). write the equation in the form ax +by = c.
choose the correct answer below.
a. 8x +y = 30
b. 30x +y = - 8
c. 8x+y = - 30
d. 30x +y = 8

Step-by-step explanation:

note : an equation is : y - b = m(x - a)    ... the point is : A ( a , b) and slope : m

in this exercice :  m= - 8     and  a= - 3    and b= -6

an equation is : y+6 = -8(x+3)

you can write :   y+6 = - 8x -24

8x+y = - 30 answer : C

C. 8x + y = -30

Step-by-step explanation:

-6 = -8[-3] + b

24

-30 = b

y = -8x - 30

+8x +8x

8x + y = -30 >> Standard Linear Equation
